“Welcome to all renewable energy enthusiasts and electronic hobbyists. Solar power, with its sustainability and vast potential, is an indispensable source of renewable energy. However, to optimally harness this power, we require a tool to monitor and control the performance of solar photovoltaic (PV) systems.
This Instructable intends to provide a detailed, step-by-step guide on constructing a comprehensive solar PV monitoring system. The system integrates a variety of components including the ACS758 sensor, ADS1115 Analog-to-Digital Converter (ADC), Xiao ESP32 microcontroller, and an OLED display. Additionally, to enhance the system’s capabilities, we will incorporate a voltage divider for accurate voltage measurement, a DS18B20 temperature sensor to monitor panel temperature, an XL7015 voltage regulator to maintain a steady power supply, and a battery connector for energy storage.
